Singles, Slabs, Sealed and Card Show Chaos
Splash & Shadow Studio started with Ludwig and Renee, two Vegas-based collectors turning a mountain of cards into a real card-show vendor brand.

ShadowWave is a desktop pricing and market-intelligence tool for Pokémon TCG vendors, built by someone running the same inventory you are. Import the collection you already track, price it against live market data, and see which of your cards are moving before the rest of the market does.
Trends in this hobby surface through influencers, after the market already moved. By the time it's a video, you're buying the top and selling the bottom.
A card that books $80 but never sells isn't an $80 card. For a vendor, liquidity matters almost as much as price, and no tool you use today measures it.
You've already built your collection in Collectr, TCGplayer, or Shiny. Retyping thousands of cards to switch tools was never going to happen.
Two parts: the desktop app where you run your collection, and a background service that watches the market for you overnight. Here's what's inside.
Bring the files you already have: Collectr, TCGplayer, and Shiny imports built in, plus plain CSV. The biggest players in the space, no retyping a single card.
Fast Movers and a Sleeper Watch on the collection you actually own, flagged before the trend hits your feed. Influencers report the wave. You'll have seen it forming.
Every card gets a plain-language liquidity read (Illiquid, Slow But Movable, Medium, and beyond) right next to the price. Because whether it sells matters almost as much as what it books.
See the real return on sending a raw card to PSA: gem rate, fees, and payout net of costs, right in the Vault. Country-to-country price gaps are next on the roadmap.
Export a pre-priced eBay Seller Hub listing file at whatever markup strategy you set. Local data dump means your collection loads instantly, no waiting on the web to refresh.
Every deal you make, whether bought, sold, or traded across the table, tracked in one place, so you finally know your real numbers.
No mockups. Every screen below is the live app, mid-beta, running real inventory.
$5,454.92 in expected profit across current holdings, per card, with gem odds pulled from real pop-report data, fees, and expected sale price after costs. Not a guess.
Cost paid, live price, liquidity tier, and raw-to-slab ROI, side by side for every card in the Vault, updated on every pricing run.
PSA, BGS, CGC: every grader, tracked and priced right alongside your raw singles and sealed product. Same Vault, no separate spreadsheet.
Collectr, TCGplayer, Shiny, or a plain CSV: drop it in and ShadowWave takes it from there. No retyping a single card.
Batch-select cards in the Vault and export a ready-to-upload eBay CSV in one click, no re-keying prices into Seller Hub.
Most pricing tools give you one number and let you assume it's real. ShadowWave labels every price and liquidity score with where it came from, so you know when you're looking at proof, and when you're looking at an estimate.
"I built ShadowWave because I was tired of pricing my own inventory off gut feel and a browser full of eBay tabs. I'm a vendor first. Every feature in here is something I needed for my own binder before it was something I built for anyone else's."
ShadowWave opens for beta testing soon. Vendors get in first. Drop your details below and you'll hear from us the moment it's ready to install.
Follow for launch newsThree tools built for our own table first. Pick the one that matches how you work.
Turn the collection you already track into printed price labels. Card name, your logo, and a QR code back to your shop, sent straight to the label printer on your table.
Fast, accurate scans of any card: see what it is, what it books for, and how fast it really sells. Build cash offers on the spot and track your collection repriced daily.
Pricing and market intelligence for your whole collection. Import what you already track, price it against live market data, and see which of your cards are moving first.
ShadowTag is an iPhone app that turns the collection you already track into printed price labels: card name, your logo, and a QR code back to your shop, sent straight to the label printer on your table. Your prices come from your file, never from the internet.
First the lookup, then the negotiation. Every card without a price on it is a question you have to stop and answer, and a number you end up defending on the spot.
Price a card too high and the customer never even asks. Price it too low and you just sold yourself short. The number you worked out at home is the right one. It needs to be on the card.
Most of your box is priced the same as it was last weekend. Reprinting all of it is a wasted roll and a wasted evening. You only need the ones that changed.
ShadowTag does not try to be your inventory system, because you already have one. It does the last ten feet: getting the price you already decided on onto the card in front of the customer.
TCGplayer, Collectr, Shiny, ShadowWave, and ShadowSnap files all import directly. Tap Import in the app, or share a CSV to ShadowTag from Mail or Files. Nothing to retype.
Set your price bands once: round up in dollar steps at the bottom, odd dollars with a cushion up top. Every label follows the rule, so a $157.65 card prints as $163 without you touching it.
Every card is New, Changed, or Printed. Import a fresh export before your next show and only the movers come back to the top. Print those, leave the rest alone.
A QR code to your shop or Instagram, your logo, the card name, and the price, laid out live at true printer resolution so what you see is what comes off the roll.
NIIMBOT D11, D110, and Nelko P21 over Bluetooth. Watch the signal strength, print a test label before you commit a roll, and it reconnects to the same printer when you get to the venue.
Select what you need, see how long the run will take before you start it, and let it go while you set up the table. Quantities from your file carry straight through.
Every screen below is the finished app running a real collection.
Export from whatever you already run your inventory in and ShadowTag reads it. Scanned a stack in ShadowSnap? Send it over and it lands here ready to print. The prices on your labels are the prices in your file, full stop.
Decide once how each tier should round and the whole collection follows, with a live count of how many of your cards land in each band.
New, Changed, and Printed are filters, not decoration. Import a fresh export and the app tells you exactly which cards need a new label, then prints only those.
Scan, tap your printer, print a test label. Signal strength is right there, so you know before the doors open whether the printer will hold the connection from under the table.
Pricing tools that phone home end up deciding your prices for you. ShadowTag never does. The number on the label is the number you imported, and nothing about your inventory leaves the device.
Just a vendor helping other vendors. No subscription, no account, no trial that quietly ends, and no upsell three screens in. Buy yourself a printer for under $30, load whatever compatible labels you like, and that is it.
Pricing checked August 2026. CardForge and DeckTradr include broader feature sets; this compares the cost and hardware choices for TCG label printing, not every feature in each product.
"I built ShadowTag after spending a night up till 3am pricing every card in my inventory. Only to find myself at the table the next day, STILL writing those prices on sleeves with a Sharpie. 😭 The work was already done. The prices just hadn't made it onto the cards.
It's free because I'm a vendor first, and this is the tool I wanted somebody to hand me."
ShadowTag is free, the way it will always be. No code, no account, no sign-up. Download it and it opens straight into your inventory. Follow Splash & Shadow on Instagram if you want to see what lands next.
ShadowSnap is a free iPhone scanner for trading cards: fast enough to keep up with a binder, accurate enough to trust with your money. Point it at a card and see what it is, what it books for, and how fast it actually sells, measured as liquidity droplets on every card. No other scanner does that. Build cash offers on the spot, track your Vault, and move your collection freely between TCGplayer, Collectr, and Shiny.
A card that books $80 but sits for a year is not an $80 card. Every scanner shows you the price. None of them tell you whether anyone is actually buying, and that is the number a deal lives or dies on.
A binder lands on your table and you have seconds to put a number on it. Guess high on slow cards and you sit on them for months. Guess low on fast movers and the seller walks. Sell speed should set the percentage.
Hundreds of cards, entered one search at a time, and the values are stale a week later. Your collection should build itself from the camera and reprice itself every day.
ShadowSnap is a fast, accurate scanner, a price guide, a liquidity read, a built-in offer builder, and a collection tracker in one camera view. Here is what's inside.
Point the camera and the card, set, number, finish, condition, and market value are on screen before the card leaves your hand, with a match-confidence badge on every result. Capture a whole binder page at once, in English plus 25,000+ Japanese and Chinese cards.
Every recognized card gets liquidity droplets, an at-a-glance read of how fast it actually sells. Full droplets move quick. Empty droplets sit. No other scanner shows you this.
Scan cards into a stack and get a suggested buy percentage informed by sell speed. Slide it where you want it, lock it in, and hand over a clean full-screen offer the customer can read.
Singles, slabs, sealed, quantities, and whole collections in one Vault, with market values refreshed daily. See what you paid, what it's worth now, and the whole price journey.
Compare raw value against potential graded value using historical population and gem-rate data, minus the fees. More information before you pay to slab a card.
Import and export CSV files compatible with Collectr, Shiny, and TCGplayer, or send a stack straight to ShadowTag to print price labels. Your data leaves whenever you want it to.
Five droplets sit next to every price. They are ShadowSnap's read on relative sell speed, measured from real market activity instead of guessed from the price tag, and they change how you buy. Fast movers deserve a stronger offer. Shelf sitters deserve a discount. Now you can tell them apart before the cash leaves your pocket.
Every screen below is the finished app running a real collection.
Thirteen cards on the table, $142.80 at market, and a suggested cash offer built from what those cards will actually do. Slide the percentage where you want it and lock it in.
Tap Show Customer and the phone becomes the pitch: every card, its market value, and the cash number in writing. No sticky notes, no mental math, no arguing about what came from where.
577 cards, $48,122.33, and not one of them typed in by hand. The Vault holds singles, slabs, sealed, and whole collections, and refreshes market values every day so the total is never stale.
PSA, BGS, CGC: the grader and the grade ride along on every slab, priced as the slab it is, not the raw card it used to be. One filter shows the whole graded shelf and what it's worth.
ShadowSnap speaks the CSV formats the big collection apps already use, and it talks to ShadowTag directly. Scan all day, then send the results wherever they need to go.
No subscription, no account, no scan limit that resets when you pay, and no "pro" tier hiding the good parts. The scanner, the liquidity droplets, the offer builder, and the Vault are all free. Built by a vendor who wanted the tool to exist, not a bill.
"Every scanner could tell me what a card was worth. Not one could tell me whether it would sell. I buy collections across a table for a living, and the difference between an $80 card that moves in a week and an $80 card that sits for a year is the whole deal. So I put that number next to the price, where it always belonged."
ShadowSnap is live on the App Store. Download it free, then DM Splash & Shadow on Instagram for the access code that unlocks the app.
Ludwig and Renee didn't start as vendors. They started as collectors: the kind who obsess over condition, argue about which sets actually matter, and have definitely stayed up too late watching market trends move (thank you thecardscience). Somewhere between a mountain of bulk and their first card show table, Splash & Shadow Studio was born.
Based in Las Vegas, they run a booth that doesn't fit neatly into one box. Pokémon singles, PSA slabs, sealed product, bulk boxes, trade binders, collection buying: if it's in the hobby, it's in the mix, and at least one of them has a strong opinion about it.
The studio also builds its own software, tested at its own table first. Ludwig has worked in software for 10+ years, which mostly means he knew exactly how these tools should have worked all along. ShadowTag prints price labels straight from an iPhone. ShadowSnap scans any card and shows what it books for and how fast it really sells. And ShadowWave, a desktop market-intelligence platform for serious vendors, opens for beta soon.
Everything is free. Not a trial, not free-until-you-rely-on-it. Free. The apps get made creatively because that's the fun part, and given away because the hobby has been good to us and giving back felt better than another subscription. Booth is our hobby, Building is our passion and TCG is how we make friends.
On the content side, Splash & Shadow is doing things differently. No boring pack openings. No inside jokes that only vendors get. Instead: something artistic, some of the normal stuff you see, but with a twist of something fun. We like pushing boundaries and finding the things that actually capture what makes this hobby feel like a real hobby (whether you've been collecting for 20 years or just pulled your first chase).
The bigger plan? Travel. New cities, new shows, new collectors. Because the cards are cool, but the people are the point.
Collectors first. Always.
